LED Technology is not just about efficiency, power and light color temperature. Luminous flux performance over lifetime and color rendering index, accordingly the spectrum, are important as well. A lot of people recognize cheap LED versions in any shops or retail stores that seem to be bluish and illuminate the space quite palely.

The manufacturing process is accompanied by variations in material and action itself. The results are white light LEDs with different characteristics. Binning systems have been introduced to support the performance of LEDs and LED products. Binning is focusing on LEDs chromaticity (light color) or luminous flux (brightness) and can be described as the grouping of the LEDs into samples with the same or closest light color or brightness.

LED Light Color – Binning System.

In a nutshell, recent studies tested different compositions of lighting spectra and found an influence on human condition. People who are sensitive to their surroundings tend to complain about headache, dizziness and even nausea when exposed to imbalanced spectra. Long term exposition is even expected to have a negative impact on human health. When buying LED light sources, retrofit kits and products have a look at the CRI or spectrum. The more balanced, the better for the people working under it.

Having power throughout your home isn’t something that you think about on a regular basis. In fact, when you flip the switch, you anticipate the light coming on. However, there may be a day when the power doesn’t work as expected. More precisely, you may find that the power in one room isn’t working while all other rooms are fine. What do you do when you don’t have power in one of your rooms?

The electricity that flows through your home powering the myriad of electronic devices your family owns is a system. There are numerous problems that can happen that could interfere in how the system works. Fortunately, when you have only one room without power, you can isolate the problem to that particular room.

Although there are many reasons you may not have power in one of your rooms, most of the problems will originate in the room since other rooms have power. The following are a few things you should consider when you are trying to isolate the problem.

Your breaker box is the point in your home in which you can safely interact with your electrical system. Within your breaker box are switches you can turn on and off to control the flow of electricity. When you have no power in one room, you may need to simply switch the breaker connected to that room off and then on again.

Many homeowners paint on occasion. In order to get a complete look for their rooms, they may take off the covers for their outlets and switches. If you have painted recently, then your switch or outlet may be the culprit.

Your covers hide all the wires running to your switches. If one of these wires were loosened while you were removing the cover, it could have caused the power outage.

Well, they told us yesterday’s Super Bowl would be the greenest one to date, but they failed to mention that as part of the plan to save energy they were going to turn the lights out in the second half.

Just kidding. This year’s Super Bowl might go down in the books for its lighting “abnormality,” but certainly there were some “bright spots” about this year’s lighting as well. Today, I’m going to reflect on  both.

We were also enamored by the flashy lights in Beyonce’s halftime show. Seriously, this show was any lighting enthusiast’s dream. It had everything. A stage with insane video effects, a guitar with incredible pyrotechnics, and 72,000 fans wearing Image via USAToday.com

What actually caused this thing?

After the lights came back on and the game ended, Entergy New Orleans, the stadium’s energy provider, and Superdome operator SMG issued this statement in an attempt to “shed some light” on the situation:

“A piece of equipment that is designed to monitor electrical load sensed an abnormality in the system. Once the issue was detected, the sensing equipment operated as designed and opened a breaker, causing power to be partially cut to the Superdome in order to isolate the issue. Entergy and SMG will continue to investigate the root cause of the abnormality.”
